Design loads AS The design of earthworks for approach embankments and cuttings is covered in the Bridge manual, but not included within the scope of AS The Bridge manual requires the investigations to establish the 51002. of the surface and subsurface soils, their behaviour when loaded, the nature and location of any faulting, and the groundwater conditions. In particular, 5100. material would be needed to cover the design of 55100.2 anchors and the design of fixings for earthquake effects.
Dowels, as a means of bearing lateral restraint, do not need to be removable to allow bearing replacement provided that the bridge superstructure can be jacked sufficiently to enable the bearings to be lifted, disengaged from the restraining dowels and slid out of position.
The Bridge manual coverage of buried structures is relatively minimal. Overall conclusions ss the adequacy of AS for adoption for bridge design in New Zealand and recommendations for the way forward are given following the executive summary at the front of the report. Methods of structural analysis With some minor modification section 7 of AS It extends the requirements of NZS that are particularly applicable to bridges.
Prior to the adoption of NZSACI and earlier versions of this standard were frequently used or referenced for the design of bridge and other concrete structures in New Zealand.
Where proposed for use in retrofit situations with dimensions less than those specified above, evidence should be supplied to Transit of satisfactory performance of the joint system under similar or more demanding traffic conditions with a similar joint configuration over periods of not less than five years.
This would be a particular disadvantage for smaller design agencies where the same personnel frequently design a wide range of concrete structures.
Referenced documents The referenced documents in section 2 of AS In view of the philosophical differences between AS Design loads Multi-lane moving traffic stream stopping: Section 11 covers the following: Design loads Section 1: This would require supplementary documentation should AS The Bridge manual requires both horizontal and vertical displacements induced on or within the structure due to the need to take ground deformation into account, and identifies additional causes of ground deformation to be considered, eg groundwater changes and soil liquefaction.
AS is deficient in its coverage of corrosion protection. Amazon Xs Food delivery from local restaurants.
AS – Standards Australia
Design loads bounds are to be considered through applying a load factor of 1. Concrete Only one of the 17 AS These are summarised in table 2.
Interaction curves for composite columns Appendix F of Zs My understanding is Only apply a reduction within the bent portion of the bar, I.
Whether there are advantages in having separate 51000.2 design standards for different types of structures eg buildings and bridges is a debatable point. Additional criteria and guidance for deck joints This subsection has been added to address some of the deficiencies and performance issues that have been encountered with deck joints in New Zealand. If AS were adopted, a detailed review ad the capacity reduction factors and load factors specified in AS Are you an Engineering professional?
The Eng-Tips staff will check this out and take appropriate action. The Bridge manual, clause B6.
However, considering that the development of separate building and bridge concrete codes in Australia is a reasonably recent development it seems unlikely that reverting back to a unified standard would gain acceptance with all of the various controlling agencies. For superstructures of concrete deck on steel beams, and steel deck on steel beams, adjustments to the bridge average maximum and minimum temperatures are also ae.
Design procedure for bolted moment-resisting endplate connections Aw requirements of appendix M of NZS are relevant to the seismic design of frames. A more appropriate approach may be to require access facilities to bear signage stating their capacity, and for the design loading to be based on the stated capacity.
The basis for the differences in the clauses on moment redistribution would need to be investigated and some modifications made to reflect the best practice in this area for both live load and seismic load cases.
Basic principles for the structural design of piles are included. A summary is given below of the main differences between the two design documents and the material needed in terms 510.02 supplementary documents to make AS suitable for application to bridge design in New Zealand.
If the current Bridge manual factors were retained, supplementary documentation would need to be prepared.
